Application filed January 26, 1907. Serial No. 354,243.

To all whom it may concern:

Be it known that we, ALBERT T. MoIL- VAI-N and GEORGE F. STOVER, citizens of the United States, residing at Olathe, in the county of J ohuson and State of Kansas, have lfiVGThtGLl a new and useful Compound for Rendering Photographs Translucent; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in the art of rendering photographs and other pictures transparent and consists in the combination of certain elements hereinafter described.

It is often desirable to employ photographs of objects persons or scenes for hand painting, but it is difficult to produce a thoroughly artistic Vroduct when. using an ordinary photograp 1.

By means of this invention, it is possible to produce a first class ainting on a Window or other substance of 11 e nature. If it be desired to ornament a window with a scenic effect, a suitable photograph is secured and the following compound is applied thereon:

one ounce of balsam of fir, one ounce of poppy oil, half an ounce of spirits of turpentine, six drops of fluid extract of alkanet root. The effect of this preparation is to give the photogra h a very desirable transparency, such as cou d not be secured heretofore. When the photograph is dried it is then in condition to receive the various colors for transforming it in to a painting.

In the preparation of the above invention it is desirable to first mix the balsam of fir, the poppy oil and the spirits of turpentine, before adding the alkanet extract.

What we claim and desire to secure by Letters-Patent is:

The process of renderin photographs transparent consisting in a p ying to photographic 1prints a com oun. prepared of balsam of r, poppy oi, spirits of turpentine and alkanet root extract,

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
